Abstract :

To study the effect of harvesting time on the quantity and quality of sugar beet, 3 harvest dates (October 22nd, November 6th& November 21st) and on the five varieties of sugar beet (Afshari, Zarghan, Shirin, Rasul& jolgheh) were evaluated. The study was conducted in factorial experiment based on complete block design with three replications in Khoy Agricultural Research Center during 2009. Cultivation operations in mid-April, based on recommendations and the same for all treatments were performed. Analysis of variance showed significant differences between cultivars in terms of sugar content, white sugar content, alkality, sodium and nitrogen impurities. Variety of Rasul sugar content and white sugar content was more than other varieties. The difference between harvesting dates of the root yield, sugar content, white sugar content, white sugar yield and sugar yield was significant. November 21st harvest root yield found with 94.360 tons per hectare more than previous harvest dates. The highest sugar content, white sugar content was related to the date of November 21st and was higher than other harvest dates. The highest sugar yield and white sugar yield respectively, 12.98 and 10.34 tons per hectare belonged to November 30th harvest. That was of significant difference rather than two other dates.
